Lake Whatcom Capital Project Plan Update

All capital projects included in the original Lake Whatcom Comprehensive Stormwater Plan have either been built or are on the County’s current six-year capital project plan, the Water Resources Improvement Program. In 2017, Whatcom County Public Works completed a plan update to identify and prioritize new water quality treatment capital projects within the county portion of the Lake Whatcom watershed (outside of city limits).

The update process included:

  • Collecting information on known surface water problems and possible water quality treatment capital projects from the public and Lake Whatcom Management Program partners.
  • Engineering analysis to identify and scope new capital projects.
  • Evaluation and prioritization of proposed projects based on preliminary cost estimates and estimated phosphorus load reduction.
  • Developing conceptual designs for priority capital projects.
  • Developing a draft and final addendum to the Lake Whatcom Comprehensive Stormwater Plan.
